减压下正丁醇〔1〕—甲基环己烷〔2〕系汽液平衡的研究

A Study on Vapour—Liquid Equilibrium of n-Butanol(1)—Methylcyclohexane(2)at Subat mospheric pressures

使用Rose—Williams平衡装置,测定了正丁醇—甲基环己烷系在300和500mmHg 压力下的汽液平衡数据.用 Herrington 经验方法,对所测数据进行了恒压下的热力学一致性检验,并用 Van Laar、Margules、Wilson、NRTL、UNIQUAC 和 UNIFAC 方程进行了热力学关联,得到了满意的结果.

Vapour-liquid equilibrium data have been determined at 300 and 500mmHg pressures for the n-butanol(1)-methylcyclohexane(2)binary system by Rose-Williams still.Tests are made for isobaric thermody-namic consistency of the determined data by Herrington empirical method,the determined data are correlated in thermodynamics by Van Laar,Margules,Wilson,NRTL,UNIQUAC and UNIFAC equations,and satisfactory results are obtained.
